virus

infective agent / malicious code

/ˈvaɪɹəs/

[C] Countable
pl: viruses

The word evokes a sense of invisible infiltration and uncontrolled replication. Whether biological or digital, the central image is an external agent that hijacks an existing system to propagate itself, often causing damage in the process. In a medical context, it carries a connotation of fragility and volatility (mutation) as well as vulnerability, since it requires a host to survive. It is used neutrally in science but often carries a tone of alarm or urgency in public health contexts. In computing, it implies a malicious, parasitic nature. While 'malware' is a broader term for any harmful software, 'virus' specifically suggests the ability to spread from one file or computer to another, mirroring the biological process.

Etymology

Derived from the Latin word virus, meaning a poisonous substance or venom, which originates from the Proto-Indo-European root wei- meaning to bend or twist. The term was adopted into medical terminology in the late 19th century to describe an infectious agent smaller than bacteria, and later transitioned into computing in the 1980s to describe self-replicating malicious code.
